How does genetic diversity contribute to the survival of a species?
Genetic diversity is important for the survival of a species because it increases the chances of individuals having traits that can help them adapt to changing environments or resist diseases. This variation allows a species to better withstand threats and increases its overall resilience.
Why is variation in traits important for the survival and adaptation of species?
Variation in traits is important for the survival and adaptation of species because it allows for genetic diversity. This diversity increases the chances that some individuals will have traits that are better suited for changing environmental conditions. This means that when the environment changes, some individuals will be better able to survive and reproduce, passing on their advantageous traits to future generations. This process, known as natural selection, is essential for the long-term survival and evolution of species.
Why is meiosis and fertilization important for survival of many species?
Meiosis and fertilization are important because they allow for genetic diversity in offspring, which increases the chances of survival in changing environments. Meiosis ensures that offspring have a unique combination of genes, while fertilization combines genetic material from two parents to create variation. This genetic diversity helps species adapt to new challenges and increases the likelihood of successful reproduction.
What 2 factors determine the evolution of a species?
Two key factors that determine the evolution of a species are genetic variation and natural selection. Genetic variation provides the raw material for evolutionary change, while natural selection acts on this variation by favoring individuals with traits that increase their chances of survival and reproduction.
Sexual reproduction provides for what to occur?
Sexual reproduction allows for genetic variation to occur through the combination of genetic material from two parents, increasing the chances of offspring survival in changing environments. It also promotes genetic diversity within a population, which can enhance the adaptation and evolution of species over time.

Why fertilized human is important?
Fertilization is important so species can have genetic variation. It is also important so the species can pass on their genes.

Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.

What is variation among members of the same species called?
Variation among members of the same species is called genetic diversity. This diversity arises from differences in genetic makeup, leading to variations in traits such as physical appearance, behavior, and susceptibility to diseases. Genetic diversity is important for a species' ability to adapt to changing environments and to evolve over time.
What causes variation within species?
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the species.
Which level of biodiversity may still be reduced after a species recovers from a threat to its survival?
Genetic diversity may still be reduced even after a species recovers from a threat to its survival, especially if the population size was greatly reduced during the threat. This can lead to decreased genetic variation within the species, making it more susceptible to future environmental changes and diseases.
What is the adaptive value of the process of crossing over as a source of variation in a species?
The process of crossing over during meiosis increases genetic variation within a species by shuffling genetic material between homologous chromosomes. This genetic diversity enhances the ability of a species to adapt to changing environments and increases the likelihood of beneficial traits being passed on to offspring. Ultimately, this can improve the species' chances for survival and successful reproduction.
How does genetic variation prevent extinction of a species?
Genetic variation allows individuals within a species to have different traits that might be advantageous in changing environmental conditions. This diversity increases the chances that some individuals will survive and reproduce when faced with new threats or challenges, helping to prevent extinction. High genetic variation also provides a larger pool of traits for natural selection to act upon, promoting the species' ability to adapt over time.
